` LASTING MACHINE Filed July 2s, 1947 -9 sheefs-sneet 9 By his ttorn'eyatented pr. 25, 19.157() UNITED STM-Es.- enriffENT oFFlc 1i., This.invention relates primarily' to lastiigma; chines, and is hereinillustrated asembodiedin' amachine for lastingthe toev endsbf Goodyear"welt shoes. It is' tovb'e understoodfhowever, that" in some aspects itis not limited to machines for" lasting shoes. of that particular type'.

In lasting ,theV toe ends of' shoes ofthe above"- mentioned type, amongothers,` it is' the common" practice to use apair of toe-embracingwipers' whicliwipe` the toe end'bf the upper heightwise results. in thewiping of. the marginalfportibn of"l the upper inwardly against a 1ip`or vshoulder on. the insole.

Fig. 14 is a cam chart showing the timing oi the movements taking placein the cycle of operations.

The machine is provided with a shoe support 2 (Figs. 2 and 9) comprisinga block l fast on the upper end of a rod 6 which is guided for upwardand downward movements in a bearing 8 formed in a crossbar l0 secured atits opposite ends (Fig, 4) to the frame of the machine. Detachably heldon the block 4 by means of the same construction as disclosed in UnitedStates Letters PatentJ No. 2,444,141, granted June 29, 1948, on anapplication of mine, is a plate l2 formed to engage and support thebottom of the forepart of a welt shoe and also to fit the inner face ofa lip a (Fig. 10) on the insole and thereby to position the shoeheightwise, lengthwise and laterally. Also mounted on the block 4 is arod i4 which is threaded in the block for upward or downward adjustmentand is provided on its upper end with a pad i5 arranged to engage andsupport the bottom of the shoe at or near its heel end. It Will beunderstood that this rod is adjusted at the proper height thus tosupport the shoe when the bottom of its forepart rests evenly on thecurved upper face of the plate I2. The movable rod 6 on which the blockl is mounted has a ball-shaped lower end i8 (Fig. 2) conned in a socketformed in a lever 26 which is pivotally supported at one end on a link22 pivotally mounted on a bracket 25 on the frame. The other end of thelever 28 is provided with a roll 26 (Figs. 2 and 4) engaged by a pathcam formed inone side of a cam wheel 28 fast on a cam shaft 30. By thiscam, therefore, upward and downward movements are imparted to the rod 6and the shoe support 2 at the proper times in the cycle of operations,as more fully hereinafter explained.

, Substantially at the beginning of the cycle of operations the forepartof the shoe is clamped against the plate l2 by a toe rest 32 mounted ona rod 34 (Fig. 2) supported by a yoke 35 which has twodownwardlyextending arms 38 (Fig. 3) slidingly mounted in guides 68 (Figs. 1 and3) on the frame. Pivotally mounted on the lower ends of these arms areblocks i2 engaged by the forked i front ends of levers Mi (Fig. 4) whichare pivotally mounted at their rear ends on a rod 66 on the frame.Supported on each lever is a roll 48 engaged by a path cam formed in oneside of a cam wheel fast on the cam shaft 36, one of these path camsbeing shown at 52 in Fig, 2. By these cams, therefore, downward andupward movements are imparted at the proper times to the yoke 36, asalso more fully hereinafter explained.

Pivotally mounted on a pin 54 in the yoke 36 is a member 55 portions ofwhich extend over and under the yoke as shown in Fig. 2, and secured onthe front of this member is a plate 58 (Figs. 2 and 3). The member 56and the plate 58 provide a bearing for the rod 3d on which the toe rest32 is mounted and also provide a recess for a spring 60 the lower end ofwhich is seated on a cupshaped flange 62 formed on the upper end of therod. Threaded in a socket in the rod is a screw 64 which extendsupwardly through the spring and through recesses in the member 56 andthe plate 58 and has thereon a flange 66 arranged to engage the memberand the plate to limit downward movement of the toe rest under theinfluence of the spring. It will be understood that by turning the screwthe toe rest may be adjusted in a downward or an upward directionrelatively to the yoke 36, and that upon downward movement of the yokethe spring 60 is yieldable after engagement of the toe rest with theshoe. Extending downwardly from the flange 62 on the rod 34 into a holein the plate 58 is a pin 68 to prevent the toe rest from turningrelatively to the member 56.

Pivotally supported on ears 16 (Figs. 2 and 3) on the front of the plate58 by means of a pin 'I2 are two forwardly and downwardly extending armsM connected together in spaced relation to each other at their lowerends by a tie bolt i6 to swing in unison about the axis of the pin l2.Formed on these arms are guideways i8 for a block 86 provided with anear 82 extending downwardly between the arms, and pivotally mounted on apin 84 in the ear 82 is a last pin 85 arranged to enter the usualspindle hole in the heel end of the last. Pivotally mounted on a pin S'lin the arms 15 is an eccentric 88 positioned between the arms and havinga handle 50 extending therefrom, the eccentric being arranged to engagethe top face of the block 86 to secure the block in any position ofadjustment along the guideways i8. Initially the arms I4 are positionedas shown in Fig. 1, downward movement thereof about the axis of the pin'l2 being limited by engagement of portions of the arms near the pinwith the front face of the plate 58. After the operator has mounted ashoe on the plate I2 and the heel-end support i6 in the positiondetermined by the plate, he inserts the last pin 86 in the spindle holein the last, adjusting the block if necessary and then locking it by theeccentric 88. When the yoke 36 is thereafter moved downwardly to applythe toe rest 32 to the shoe the arms 15 in response to that movementswing a short distance about the axis of the pin T2 with a toggle-likeaction tending to force the last pin 86 in a heelward direction. In thismanner force is applied to the last and shoe to seat the lip of theinsole at the end of the toe firmly against the plate i2. Thereafter, inthe operation of the machine on the shoe, the last pin 86 assists inholding the shoe against lengthwise movement in a heelward direction,thus preventing excessive strain on the lip of the insole at the end ofthe toe. For better insurance that the last pin will be held rrnlyagainst any force tending to displace the shoe in a heelward direction,the top face of the block 80 which is engaged by the eccentric 88 isinclined relatively to the arms 14 lengthwise of the arms, asillustrated in Fig. 2, to render the eccentric more eiective as a lockfor the last pin.

The ball-shaped lower end I8 of the rod 6 permits the shoe support 2 toswing in directions widthwise of the shoe about the axis of the rod. Thepin 54 is coaxial with the rod 6, and therefore the toe rest 32 and thelast pin 86 may swing with the Shoe suport about the same axis. Suchswinging movement may take place in the course of the operation of themachine in response to pressure of the wipers (hereinafter described) onone side or the other of the toe end of the shoe to permit the shoe toadjust itself in this manner to the wipers.

Mounted to turn about a kushing 92 (Fig. 2) on the rod 34 is a member 94which may be termed a wire looper, this member being pressed up againstthe member 56 and the plate 58 by a spring 96 mounted between it and thetoe rest 32. This wire looper is not herein shown in detail, but it isof essentially the same constructionrasra'- device` provided forthefsame1 purpose inV accordance with th'e'disclosure of Letters Pate@ent;No:-2,160;846, granted'on June 6, 1939, on'lan#y applicationv`^ ofFSC; Eastmans and A.

The manner of operation of the machine will now be more fully explained,in so far as is necessary for an understanding of the invention, withreference to the cam chart (Fig. 14). The machine having been providedwith a shoe-positioning plate I2 and with wipers |38 and |40 suitablefor the style and size of shoe to be operated upon, the operatorpresents a shoe to the machine in the position determined by engagementof the plate I2 with the bottom of the fore part of the insole and theinner face of the lip a of the insole, the bottom of the shoe at or nearits heel end resting on the pad IS properly adjusted heightwise of theshoe. When thus presenting the shoe the operator swings the connectedarms 'I4 upwardly to provide for clearance between the shoe and the lastpin 80, after which he inserts the last pin in the spindle hole in thelast. If the shoe is the i'lrst one of a given style and size to beoperated upon, the block 30 will be unlocked by the eccentric 88 topermit it to assume the proper position along the arms 14, after whichit will again be locked by swinging the handle 90. As the shoe is thuspresented, the toe end of the upper is spread outwardly over theretarder ||4, which extends upwardly at this time somewhat beyond theplate I2 as illustrated in Fig. 9.

VAt the beginning of the cycle of operations, initiated by depression ofthe treadle 208, the yoke 30 is moved downwardly to cause the toe rest32 to clamp the shoe against the plate I2, the spring 60 beingcompressed after engagement of the toe rest with the shoe. In responseto this movement of the yoke the arms 'I4 swing a short distance aboutthe axis of the pin 'I2 with a toggle-like action on the last pin 86,thereby forcing the last in a heelward direction to seat the lip of theinsole at the end of the toe rrnly against the plate I2. Simultaneouslywith the downward movement of the yoke 36 both pairs of wipers |30 and I40 are advanced toward the shoe and are closed about the toe above theedge of theshoe bottom, the wipers |40 being advanced and closed fartherthan the wipers |32. Thereafter the shoe support 2 and the yoke 33 aremoved upwardly together, the shoe support beginning its upward movementbefore the yoke and thereby further compressing the spring 60. In thismanner the shoe is moved upward to cause the wipers to wipe the upperheightwise of the last, the shoe adjusting itself laterally to thewipers by reason of the provision for swinging movement of the shoesupport about the axis of the rod 6. Substantially at the beginning ofthe upward movement of the shoe support the .cani |32 releases the lever|28, whereupon the spring I 34 moves the retarder II4 farther upwardlyto clamp the upper yieldingly against the wipers |40, as shown in Fig.10. The retarder, therefore, cooperates with these wipers in applying apull to the upper as the shoe is moved farther upwardly, and at the sametime the retarder is moved outwardly lengthwise of the shoe in wipingengagement with the upper by reason of the swinging of its L-shapedsupporting members |20 about the studs |22 in response to the upwardmovement of the shoe support. By reference to Fig. it will be seen thatthe wiping of the upper heightwise of the last is begun by the auxiliarywipers |40 which are in eective wiping positions at that time while themain wipers |38 are somewhat retracted. This is advantageous because thewipers |40, shaped as yhereinbefore described,

conform more closely to the contour of the upper onV the last at adistance from the edge of the last bottom than would the wipers |38. Inthe course of the upward movement of the shoe, however, the main wipers|38 are moved farther inwardly to effective wiping positions and theauxiliary wipers are somewhat retracted, as indicated onthe cam chart,so that the wiping of the upper vheightwise, of the last is completed(Fig. 11) by iliarywipershave secured an effective hold on' the upperbut before they complete their inward movements. Prior to the completionof the movements of the auxiliary wipers also the cam |32 moves theretarderl I4 downwardly to release the margin of the upper if the latteris still between it and these wipers. The machine comes to a 'stop at190 of the cycle with the auxiliary wipers holding the upper in lastedposition as shown in Fig. 12, just prior to which time the7 shoe supportis raised slightly to relieve somewhat the pressure of Vthe auxiliarywipers heightwise of the shoe on the portion of the upper wiped over thefeather of the insole.

While the machine is thus at rest the operator is aiorded the sameopportunity as in operating the Ymachine disclosed in Letters Patent No.2,160,846 to remove the end of the binder wire from the previouslymentioned wire looper and to attach the looped end of the, wire to atack at the left-hand side of the shoe bottom, after which he appliesthe wire about the toeover the top V'faces of the auxiliary wipers |40and starts to pull it inwardly between these wipers and the upper at theextreme edge of the shoe bottom. While continuing his pull Yon the wirehe starts the machine again, whereupon the shoe support is raisedfarther to permit the wire to be pulled in against the upstanding marginof the upper opposite the lip of the insole. The shoe support is thenmoved downwardly again to restore the full 4pressure of the auxiliarywipers on the overwipedupper, after which the machine comes once, moreto a stop at 270 of the cycle. The operator then twists kthe wire arounda tack at the right-hand side of the shoe bottom and severs theportionof the wire thus applied to the shoe from the remainder of the wire.Thereafter he starts the machine again to cause it to complete itscycle, the parts being returned to their starting positions. He thenswings the arms 14 upwardly to withdraw the last pin 86 from the lastand removes the shoe.

Novel features of the shoe-positioning and holding means hereindisclosed are claimed in United States LettersV Patent No. 2,486,535,granted November 1, 1949.

, 10. In a lasting machine, a pair of wipers shaped to conformsubstantially to the contour of an Yupper about the toe end of a last ata distance from the edge of the last bottom, another pair of wipersshaped to conform substantially to the contour of the upper about thetoe near the edge ofthe last bottom, means for moving the lastIVheightwise relatively to said wipers, means for advancing and closingthe first-named pair of wipers about the toe into positions to causethem Vto wipe the upper heightwise of the last in remeans for movingsaid retarder heightwise of the last into upper-clamping position afterthe first-named wipers have been advanced and closed about the toe.

11. In a lasting machine, wipers shaped to conform substantially to thecontour of the margin of an upper opposite a lip or shoulder on a weltshoe insole on a last about the toe end of the insole, other wipersshaped to conform substantially to the contour of the upper around thetoe opposite the edge face of the insole, and means for wiping the toeend of the upper heightwise of the last by said first-named wipers at adistance from the edge of the insole and then by said other wipersnearer the edge of the insole and for thereafter wiping the upperinwardly against the lip or shoulder of the insole by the rst-namedwipers.

l2. In a lasting machine, wipers for wiping the marginal portion of anupper about the toe end of a last inwardly over an insole on the lastand against a lip or shoulder on the insole, said wipers being shaped toconform substantially to the contour of the margin of the upper oppositesaid lip or shoulder, other wipers shaped to conform substantially tothe contour of the upper around the toe opposite the edge face of theinsole, means for effecting relative movement of the last and saidwipers in a direction heightwise of the last before the upper is thuswiped inwardly over the insole, and means for positioning the wipers insuch relation to the last in the course of that relative movement as tocause the first-named wipers to wipe the upper heightwise of the last ata distance from the edge of the insole and the other wipers thereafterto complete the wiping of the upper heightwise of the last.

13. In a lasting machine, wipers for wiping the marginal portion of anupper about the toe end of a last inwardly over an insole on the lastand against a lip or shoulder on the insole, said wipers being shaped toconform substantially to the contour of the margin of the upper oppositesaid lip or shoulder, other wipers shaped to conform substantially tothe contour of the upper around the toe opposite the edge face of theinsole, means for effecting relative movement of the last and saidwipers in a direction heightwise of the last before the upper is thuswiped inwardly over the insole, the first-named wipers being arranged towipe the upper heightwise of the last at a distance from the edge of theinsole in response to that relative movement, and means for moving saidother wipers inwardly toward the last into positions to continue thewiping of the upper heightwise of the last and for retracting thefirst-named wipers outwardly from the last prior to the completion of said relative movement.

14. In a lasting machine, wipers for wiping the marginal portion of anupper about the toe end of a last inwardly over an insole on the lastand against a lip or shoulder on the insole, said wipers being shaped toconform substantially to the contour of the margin of the upper oppositesaid lip or shoulder, other wipers shaped to conform substantially tothe contour of the upper around the toe opposite the edge face of theinsole, means for effecting relative movement of the last and saidwipers in a direction heightwise vof the last before the upper is thuswiped inwardlyA over the insole, and cams associated respectively withsaid first-named wipers and said other wipers for controlling them withrespect to movements lengthwise and widthwise of the last, said camsbeing so formed as to cause the nrstnamed wipers to wipe the upperheightwise of the last only at a distance from the edge of the insole inresponse to said relative movement and the other wipers thereafter tocomplete the wiping of the upper heightwise of the last while thefirst-named wipers are in retracted positions.

15. In a lasting machine, wipers for wiping the marginal portion of anupper about the toe end of a last inwardly over an insole on the lastand against a lip or shoulder on the insole, said Wipers being shaped toconform substantially to the contour of the margin of the upper oppositey said lip or shoulder, other wipers shaped to conform substantially tothe contour of the upper around the toe opposite the edge face of the insole, means for effecting relative movement of the last and said wipersin a direction heightwise of the last before the upper is thus wipedinwardly over the insole, means for positioning the wipers in suchrelation to the last in the course of that relative movement as to causethe rst-named wipers to wipe the upper heightwise of the last at adistance from the edge of the insole and the other wipers thereafter tocomplete the wiping of the upper heightwise of the last, and a retarderfor clamping the upper on said first-named wipers to apply a pull to theupper as it is wiped heightwise of the last.
